There have been rumors about Sergio Ramos looking to join PSG after leaving Real Madrid as a free agent. But there is something could be complicating things for him as according to the French "Le10 Sport" website, Nasser Khelaifi president PSG, specifically wants to return Brazilian defender David Luiz to PSG,
Luiz announced his departure from Arsenal at the end of last season, while French league duo Marseille and Rennes showed interest in the player.
If PSG manages to convince Ramos to join their team, then it's a very good recruitment in my opinion, PSG have one goal, and it's basically to win the champions league, acquiring the services of Sergio Ramos who is a multiple time winner of the CL can give then an extra boost and motivation to go on and win the crown for the first time.
I can understand why PSG's president want's Luiz rather, he is an ex player and prolly had a very good relationship with the club owner during his stay in France, thus Nasser wants to compensate him in this way, imo, I think it's what's best for the club that needs it be done, and the best looks like signing Ramos instead of David Luiz.
